Soft Raid0

[husskii]

Hi I just purchased a new server which came with 2x 750GB sata HDD's, It also have debian lenny installed and I would like to setup soft raid0 so they I can get the following partition layout..

Partition layout:
RAID 0 - / - 20 gig
RAID 0 - /home - the rest

can someone please show me how, Ive done some google searches and also looking in help guides, and I found a guide for mdadm, but having not done this before, I am getting lost..

my current config in webmin is

/dev/md1 	Yes 	Mirrored (RAID1) 	5 GB 	/dev/sda1 | /dev/sdb1
/dev/md2 	Yes 	Mirrored (RAID1) 	693.13 GB 	/dev/sda2 | /dev/sdb2

or if I run the

dh -f

command in putty, I get this

Filesystem            Size  Used Avail Use% Mounted on
/dev/md1              5.0G  669M  4.1G  14% /
tmpfs                 3.9G     0  3.9G   0% /lib/init/rw
udev                   10M  2.7M  7.4M  27% /dev
tmpfs                 3.9G     0  3.9G   0% /dev/shm
/dev/md2              688G  198M  653G   1% /home

Could really use the help...

Thanks
